The trig function required to find the normal force acting on an object that is resting on an incline.
What is cosine?
An object resting on a surface stays at rest until the force acting on it exceeds this value
What is the maximum static friction?
A measurement that is due to the combined effects of gravity, other forces, and any acceleration of an object.
